Failed to find the "quick slideshow" option, either on the program or on the instructions PDF. Is there any topic/guide on that, please?

Explanation of desired feature:

I very often want to move to another image while I'm already in fullscreen mode seeing one file. At that point many image viewers have a functionality/hotkey to simply jump to another random image on the same path. This really helps when you want to serendipitously browse for a large set of images. Have you pls considering implementing something like that?
